The effects of the following biotechniques were discussed:embryo transfer, multiple ovulation, in vitro fertilization of oocytes, embryo and semen sexing,eloning as well as creating transgenic animals. Application of these biotechniques increasesselection intensity and descreases genetic variability (except for ereating transgenic individuals).Moreover, modification of classical models of evaluation of the genetic value of animals is necessary.}, title={Postęp genetyczny u zwierząt w świetle stosowania nowoczesnych biotechnik gamet i zarodków}, type={Tekst}, URL={http://www.rcin.org.pl/Content/155723/PDF/POZN271_189961_biotechnologia-1993-no2-szwaczkowski.pdf}, keywords={biotechnologia}, }
